ARTIFICIAL LIMBS FOR AMPUTATIONS THROUGH THE THIGH
There are two entirely different modes of fitting:
I. For amputations above the condyles, in which weight must always be borne upon the tuberosity of the ischium through the top of the bucket.
II. For amputations through the condyles (or for disarticulation of the knee) in which a direct end bearing may suffice.
I. Apparatus with Bearing upon the Ischium
(Amputation above the condyles.)
In the construction of an artificial limb for amputation through the thigh two entirely different principles may be used, according as it is desired to make the patient walk upon a rigid shaft, that is to say upon a peg, or upon an artificial leg proper, in which the knee bends in walking (known as the American leg).
But whichever principle is adopted, whatever material is chosen, wood or leather, and however exact the fit in the bucket may be, certain common rules govern:—
1. The shape of the top of the bucket by which it is fitted to the top of the thigh and its bearing upon the ischium.
2. The attachment of the limb to the trunk.
